To aZZ whom it maylconcern;

Be itknown that I, JOHN N. HELTZEL, a citizen of the UnitedStates,residing at Warren, in the county e of Trumbull and State of Ohio, haveinvented a new and useful Concrete-Mold-Form Stay, of which thefollowing is a specification.

This invention relates to molding apparatus and more particularly toportable and adjustable concrete form stays. l

Theprimary object of the invention ,is to providea means for adjustablyand removably supporting the side walls of the concrete form/toA permitthesame to be used in connection with concrete structures requiringvarious heights.` p

A further object of the invention is to provide means carried by thestay forl restricting the movement thereof when the same is being driveninto the ground `surface on which the mold is being set up.

Vith the foregoing and other objects in view which appear as thedescription proceeds, the invention resides in, the vcombination andarrangement of parts vand: in the details of construction` hereinafterydescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed without de )arting from the'spirit of theinvention.

eferring to the drawings Figure'l illustrates a side elevational view ofthe stays and concrete form supported thereby, one end of the form beingbroken away.

Fig. 2 illustrates a sectional view taken on line 2--2 of Fig. 1, and

' Fig. 3 is a top plan view ofV astay with the adjustable bracketpositioned thereon.

Referring to the drawings in detail, reference character 5 designates astay including right angle flange members 6 and 7, the lower ends ofsaid flange members 6 and 7 being tapered to form the pointed end 8, tofacilitate the driving of the stay into the ground surface on which themold is to be assembled.

Disposed directly above the pointed end 8 of the stay is a brake, inform of a right Vangled-plate, including Vflanges 9 and 10,

the flange 9 thereof being secured to the VVflange 6 by means of rivets11 passing through suitable openings 'provided in the flanges 6 and 9. l

Specification of Letters Patent. Patented J une 29, 1920. A Applicationined octo'ter 4, 1919. serian No. 323,469.

As shown, the flange 10 extends at lright angles with relation to theflange 9, and is relatively'wide to engage the ground Vsurface when thestay is driven into the ground, to prevent orl restrict the movement ofthe stay into the ground, to vprevent the stay from being driven' toofar, and to insure a relative height ofthe various stays used inthe moldconstruction.

. The flange 6, which when positioned forms the rear flange of the stay,has its rear ledge provided with notches as shown at 12,`the distancebetween the notches varying to provide various heights and adjustmentsfor the bracket 13 to be more fully described.

4 Employed with each of the stays, is a rekmovable bracket-member 13which is curved downwardly as at 14, ythe lower extremity thereofterminating in an 'upwardly extending hook member 15, to receive thedownwardly extending flange 16 of theconcrete form 17. Y

VAs vs'hownby, Fig. 3 of the drawing, the bracket member 13 is providedwith a'substantially L-shaped notch or slot 18, the por-` tion 19thereof being widerthan the width of the flange 7 over which the sameoperates, to permit the bracket, when positioned on the stay,to falldown into a position to vclosely engage the flange 7 of the stay, and

at the same time permit the bracket to be moved upwardly in order thatthe bracket may be moved from the notch in which the same is engaging,to another position of ad- 4 justment.

The concrete form 17, forming a part of the invention includes a bodyport1on-18,which when in position lies at right angles with relation tothe flange 7 of the stay, the upper end 19 thereof extending at rightangles to the body portion 18', the extreme edge of said right angleportion 19 extending at right angles thereto and lies in a position toengage within the hook member 15 of the bracket 13.

The lower extremity ofl the body 18 also extends at right angles as at20, and has its extreme edge extending upwardly as at 21 to closelyengage the flange 7 of the stay in order that the same will be held inits horizontal position, against displacement.

In operation, the stays 5 are positioned in the ground surface until thebrakes, secured thereto engage the ground surface to 2 F u u 1,345,179.

prevent the stays from being positioned too far into .theground surface,and to insure uniformity in the heights of thestays;

The bracket members 13 arenow positioned in the proper notchesof 'thestays,"

crete mold, but it is of course obvious that two of such structures arepositioned in spaced relation with each other to `form the oppositesides of the mold, to permit the plastic concrete to be positionedtherebetween. u

Having thus described my invention,what I claim is Y y 1.v In aportable"mold, stays including angle irons, one of the walls of each ofsaid stays having notches, a bracket member positioned on each of thestays, said bracket member having a substantially L-shaped slot formedtherein, and Vadapted to embrace the stay, one of thel walls of saidL-shapedslot coperati'ngfwththe notchedV walls of the stay for holdingthe bracket in various positions of adjustment, and means on one end ofsaid bracket for securing a concrete form thereto.- Y Y u 2. `In 'aportable mold, stays, each of said vrestrictin'gf .'novement thereof uground surface on which the mold is supstays being provided with anotched portion,

bracket, and means carried by the stay for into lthe ported. Y Y

3. In a portable mold, stays, each of said 'stays vhaving a plurality ofnotches formed along one of the edges thereof, a bracket having a slotembracing the stay, one of thev a bracket supported on each oft'hesestays, a ,concrete form removably supported by the walls of said slotcooperating' with Vthe notches and eans carried bythe stay forrestricting -movement thereof y,into the groundsurface,` on whichthelmold is supported. 'f f 4. In a portable mj'old, stays, each offsaid stays being provided withja notched portion, a vbracket supportedyby* each 'ofthe stays, eachv of said "stays having a slotted portionembracing the bracket, -one of the walls of said slotted Vportionl'coperatingwith the' notches lfor supporting the bracket in variousVpositions of adjustment, Vand said bracket being curved downwardly tosetup i a binding actionl between theV bracket vand stay, and amovab'leform 'supported by the bracket. i 1
